Hydroxyapatite of plate-like morphology obtained by low temperature hydrothermal synthesis

Abstract

The morphology of hydroxyapatite crystals formed in hydrothermal reaction of calcium EDTA complex with KH2PO4 at 120 °C depends on the pH value of the reaction medium. Bone-like platy microcrystals were prepared at pH 6, while at higher pH values rod-like species were obtained.
